Hi,
I'm using the EDCommon socket framework, which is sub-classed from the
NSFileHandle
class and used with neetwork sockets.
I'm working on the part of my application that wants a timeout when no
data is
received within a certain period of time.
I know there are zillions of ways to do this, and I'm sure that no
matter what way
I choose, it's always going to be a bad decision or NOT the Mac way of
doing things,
so seek some advice on the best way of doing this.
So I was thinking of doing the following:
[mSocket waitForDataInBackgroundAndNotify]; <--- I would call this
when waiting for data.
if (noAnswerTimeout == nil) {
noAnswerTimeout = [NSTimer
scheduledTimerWithTimeInterval:timeoutperiod
target:self
selector:@selector(noAnswer:)
userInfo: nil
repeats:NO];
}
- (void)noAnswer:(id)receiver
{
// Not sure if I want to terminate the Notification or not - ANY ADVICE
// And I do what I have to do to deal with the timeout here
// of course we have to do this to ditch our timer when done.
[noAnswerTimeout invalidate]; // disable timer, and release it.
noAnswerTimeout = nil; // NUKE our reference of course
}
Anyway, this is ONE approach I'm considering. But due to the fact
there is such weak
documentation available on the EDCommon framework, it don't describe
how to deal
with NO responses coming back from the network... Nor is the
NSFileHandle adept
in dealing with this.... The uncertainties are:
1) Do I have to do anything when I want to stop the "listen" thread
spawned
when "waitForDataInBackgroundAndNotify" is called?
2) If so - what do I do.... and of course I just have NO CLUE what
happens when
there isn't any data to wait for, nor can I find any info on how
to deal with this.
And of course I have my OWN things to do, if no data arrives within a
specified
period of time.
Any advice? Please be liberal and generous with Source code examples
if you
care to help me out. I'm really new at this... I don't want all the
GORY details,
I just want to know how it all works together... IE: names and
functions of
Delegate callbacks and how to deal with them.... Starting and ending
Notification
threads... etc.
Thanx
JD
